I will OC a 4770k POSSIBLY with SLI 780 (I will not now but in the future maybe). I will be gaming and doing video/photo editing. I was going to get the seasonic 80+ gold 750W PSU but I'm reading that I should have at least 850W. Any recommendation on a reputable 1000W PSU?
EDIT: But if you are set on 1000watts, d4v0's recommendations, as stated, are all good. Personally I would be partial to the Seasonic... But XFX is great too (they use the same units as seasonic i believe, have been running an old xfx for almost 4 straight years now...)
